Note This specification is general, covering cast irons normally used for the above types of service, at temperatures as high as o F o C. Last previous edition approved in as A—71 This specification covers gray iron castings exposed to elevated temperatures for non-pressure containing parts such as grate bars, stoker links, stoker parts, oil still furnace parts, firebox parts, ingot molds, glass molds, caustic pots, and metal melting pots.
A39 castings shall be free from injurious defects. We need your help to maintenance this website. It is the intention of this specification to classify the irons in accordance with their carbon content equivalent, wherein the equation for its calculation is given herein. The alloying elements, which, in addition to chromium, are commonly added to improve these properties, are copper, molybdenum, nickel, and vanadium. Need more than one copy?
